The text of IEC Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following: a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard' b) Comma (.) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker. In this adopted standard, reference appears to certain International Standards for which Indian Standards also exist The corresponding Indian Standards, which are to be substituted in their respective places, are listed below along with their degree of equivalence for the editions indicated: International Standard Corresponding Indian Standard Degree of Equivalence IEC 61020-1/IEC QG 960000 (1991) Electromechanical switches for use in electronic equipment - Part 1: Generic specification IS QC 960000 : 1995/IEG QG 960000 : 1991 Electromechanical switches for use in electronic equipment: Part 1 Generic specification Identical IEC 60068-1(1982) Environmental IS 9000 (Part 1) 1988 Basic testing - Part 1: General and guidance environmental testing procedures for electronic and electrical items: Part 1 General (first revision) Technically Equivalent Only the English text of the International Standard has been retained while adopting it as an Indian Standard, and as such the page numbers given here are not the same as in the lEG Publication.
